S-35710/20 Series Convenience Timer ICs for Automotive Use

ABLIC's devices compare the timer value and the value written to the internal register and then alert when the values match

Image of ABLIC's S-35710/20 Series Convenience Timer ICsABLIC's S-35710 and S-35720 series convenience CMOS timer ICs operate with low current consumption and are suitable for the time management of relative time. These devices compare the timer value and the value written to the internal register and then output an interrupt signal when the values match each other.

The S-35710M timer is a 24-bit binary-up counter; the internal register data can be set freely by users via a two-wire serial interface. The time before the occurrence of an interrupt signal can be set freely. Since these devices have a built-in quartz crystal, a matching assessment of the IC and the quartz crystal is unnecessary. They are available in a TMSOP-8 package.
